Jon Voight has accused Sky News of propagating “left-wing media spin” in an interview on the channel on Wednesday.

Speaking from the Republican National Convention in Florida, the actor made the bizarre claim after presenter Anna Jones asked a question about Mitt Romney’s image.

The accusation that Sky News engages in left-wing media spin will amuse many Brits, given its Murdoch-owned sister channel to Fox News is regarded by many in the UK as leaning openly to the right.

"I think the main media frankly in this country and probably around the world has not really covered him [Romney] as thoroughly as possible," he said.

Asked by Jones whether he thought Romney's stiff image was making it hard for Republican activists to get excited about his candidacy, Voight responded: "Lets cut right into that, thats exactly what I expect the left wing media to express."

Sky News, which is partially owned by Murdoch's News Corporation, has to abide by the impartiality rules that govern broadcasting in the United Kingdom.

"There is no lack of enthusiasm here and if you saw the speeches here," Voight insisted. "if you saw Ann Romney's speech… if you saw Chris Christie's speech, you'll see that everyone is extremely excited here and very much behind this man.

Voight added: "It's this spin, it's very hard, he is such a good fellow, he is an honourable guy, he is very intelligent."

"They have made this image of him that is totally other than he is because they can't really address him, they can't find any way to bring him down."

Voight said the Democratic Party led by president Obama was a "propaganda party" that had "invented a new Romney".

"You have just reflected some of the information that has been given out," he said of Jones' line of questioning.

"I think that the last three and a half years has been a really rough three and a half years, we have been weakened in every way.

"It's not hard to find someone who is better than the present president, but Mitt Romney is gifted in the things we need and the world needs."

Voight, who has played a series of political characters including President Roosevelt, also told Sky News that Hollywood was dominated by an intolerent "left wing".

"We have a left wing that is very strong, very strident, they recommend themselves as mild mannered and tolerant, but they are not," he said

"Once people get to know Mitt Romney in a proper fashion they will be very enthusiastic," he predicted.

He also praised Romney's running mate Paul Ryan as an "extraordinary guy" who could deal with the "serious problems" facing the US and the world.

Despite his criticisms of the broadcast media, Voight took time to flirt with his female Sky News interviewer in London.

"I wish I could see your face, I know you're an attractive young woman and I'd like to see you," he said. After Jones said she was not as young as he thought, he added: "For me you're young, you're a chicken."

Voight also hit out at the media during an interview with Channel 4 News on Wednesday, telling Matt Frei: "Listen to me, I'm going to get angry."

Before catching himself and adding: "You got to take care of this Brit, he's an ally."

The Deliverance star is well known for his outspoken political views on the Democrats. In July, Voight accused the “false prophet” president of bringing “chaos and socialism” to the US on Bill O’Reilly’s show, while on Tuesday he accused the administration of outright “media control”.

Yesterday Voight told Reveal Politics at the convention that he thought Obama was a Marxist.

"Well, his father was a Marxist — of course he was influenced by it,” he said when asked. “His mother, who led him towards his father’s Marxism – yes. His mentor was a fellow by the name of Frank Marshall Davis, he was a communist. And, of course, his alliances from that time on."

And he told the Daily Caller website that the American media had been "taken over" by the Obama administration.

“It’s not less than what has happened in Venezuela with Hugo Chavez, really, because you can’t get the information through," he said.

"I’m giving you this because I want to get the press my opinion. You can put it in any way you want to. But, it’s become pure propaganda and we should be appalled.”
